A Time‐Centred Perspective on Classroom‐Based Physical Activity

European Journal of Education, Volume 61, Issue 3, September 2026.
ABSTRACT Schools are recognized as a key setting for preventing physical inactivity–related health issues early in life. Despite schools offering a rich set of opportunities to integrate physical activity (PA) without disadvantages for learning, those opportunities are often underutilized in ‘traditional’ educational environments where PA is primarily ...

Parvicapsula pseudobranchicola in the northeast Pacific Ocean is rare in farmed Atlantic salmon Salmo salar despite widespread occurrence and pathology in wild Pacific salmon Oncorhynchus spp.

Parasites & Vectors, 2023
Background Infection with the myxozoan parasite Parvicapsula pseudobranchicola causes disease in wild and farmed salmonids in Norway. In the northeast Pacific Ocean, the parasite has been reported in Pacific salmon Oncorhynchus spp.

Carotenoid pigments in chum salmon - II. Behavior of carotenoids in the chum salmon Oncorhynchus keta during development.

NIPPON SUISAN GAKKAISHI, 1984
As part of the historical study of carotenoids in the chum salmon, the behavior of carotenoids was investigated duing development. The carotenoids which were stored in the eggs during the anadromous migration period, stayed in a constant quantitative (0.677-0.687mg/100g) and compostion ratio, with a 76-80% astaxabthin rate, until hatching.

The Staircase Chart: Visualising Vertical and Cross‐Shelf Movements and Dispersal of Early‐Life Fish, Applied to Japanese Jack Mackerel

Fisheries Oceanography, Volume 35, Issue 5, Page 689-703, September 2026.
ABSTRACT Dispersal during early life stages is a critical process shaping marine fish connectivity and population dynamics, yet direct field observations at the individual level remain elusive. This has limited our understanding of the factors controlling dispersal, including the impact of active swimming by larvae and juveniles. Here, we present a new

Amino acid composition of chum salmon gonadotropin.

NIPPON SUISAN GAKKAISHI, 1977
The amino acid composition of chum salmon gonadotropin (s-GTH) was compared with that of carp gonadotropin (c-GTH). S-GTH has more glutamic acid and less valine and tyrosine than c-GTH. Moreover s-GTH was compared with the mammalian gonadotropins. S-GTH resembled ovine follicle stimulating hormone (o-FSH) in the number of histidine, arginine, aspartic ...

Chemical Optimization of Temporin A–L Peptides: From Native Isoforms to Enhanced Antimicrobial Analogs

ChemMedChem, Volume 21, Issue 15, 14 August 2026.
Temporins, among antimicrobial peptides, are short frog‐derived molecules with potent antibacterial activity. This review highlights chemical optimization strategies applied to temporins A–L, showing how sequence tuning modulates structure, stability, and selectivity, enabling improved activity against resistant pathogens.

Nutritional Composition of African Catfish (Clarias gariepinus) in Ghana: Effects of Culture Conditions, Feed and Processing

Aquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.
This review synthesizes current evidence on the nutritional composition of African catfish (Clarias gariepinus), with emphasis on Ghanaian aquaculture. The species is a valuable source of high‐quality protein, essential amino acids, minerals and vitamins, although lipid composition varies widely.

Monitoring of salmon reproduction on spawning grounds in the Amur River in 2017–2024

Известия ТИНРО
Reproduction of pacific salmon in the Amur River basin was monitored during 8 years using standard methods of fisheries science. The data indicate weak reproduction of pink salmon and the summer and fall chum salmon. Distribution density of the fall chum

Indigenous sex-selective salmon harvesting demonstrates pre-contact marine resource management in Burrard Inlet, British Columbia, Canada

Scientific Reports, 2021
To gain insight into pre-contact Coast Salish fishing practices, we used new palaeogenetic analytical techniques to assign sex identifications to salmonid bones from four archaeological sites in Burrard Inlet (Tsleil-Waut), British Columbia, Canada ...
